Black for me. I'm one of those that gets really distracted by the white bezel, especially since I primarily use my iPad in bed and the black just vanishes in the dark.
I'm waiting for a silver/white retina Mini. Gonna get a brown Apple Smart Case to match the brown leather case on my gold 5s.
I was really surprised to find how much I didn't like the Space Grey iPad when I finally saw it. The colour works better on a phone IMO, though I bought the phone in gold. So I guess my answer is that if I was going to buy the iPad Air (which I'm not because it's not unbelievably light compared to my iPad 2 nor does it feel much smaller), then the iPad that I would buy would be in silver and white, just like my 2 and my Mini.
Maybe I'm missing something but what does the color of the ipad have anything to do with the color of the 5s?
You would have to think that it's probably a given that the 2014 models will come in Gold (and have TouchID).
I had the black iPad Mini, but I sold that and went for the black iPad Air. I like both white and black for the iPhone, but I don't like white on the iPad. I guess it's because of the size.
